1 CurveAnalyzer - Presentation

2 CurveAnalyzer - introduction Optimal solution for elaboration of 2D profiles Starting from building of simple geometrical elements and relationships between them, dimensioning & reporting up to sophisticated curve analysis of profiles including curve re-calculation procedures, comparison and best-fit algorithms, filters, application of variable tolerance field etc. All this, based on simple data structure, completely visual interface, allowing to have immediate control over the evaluation process.

3 CurveAnalyzer - philosophy Perfect companion to any measurement software It must let you go smoothly Intuitive, simple, efficient and powerful. Just working Concentrainting on the essential and keeping in mind the form. Fast and easy for the simple tasks, extensive for complicated elaborations. CurveAnalyzer does not intend to substitute any measurement software, but moreover to be a companion to it.

4 CurveAnalyzer Integration Integration with PC-DMIS available via automation interface exposed by PC-DMIS type library. Importing Points, Lines, Circles, Scans (as point sequences) into CurveAnalyzer. Exporting Curves (point sequences) as vector points or as scans. More detailed view of the integration with PC-DMIS is given in next chapters. Integration with other software importing / exporting occurs via corresponding file interface exposed by the program. New interfaces may be added by request. Keeping this interface simple is a key to keep the whole system stable.

5 CurveAnalyzer Features 1/2 Object Handling Handles object of the following types : Curves (defined by point sequences), Circles, Lines, Points, Texts, Images, Dimensions. Unlimited number of these objects can be handled within one session. Importing Data Integrated interface from QUINDOS and PC-DMIS. Freely programmable ASCII file interface, importing of DXF files, importing of MEA Files produced by Tutor scans, importing of PRF files produced by Taylor Hobson measurement software, importing of milling circular interpolation path. Customized importing routines can be developed on request. Exporting Data Integrated interface to PC-DMIS, exporting point data as DXF, ASCII format, milling circular interpolation path. Exporting dimensions to PCL files, DFD+DFX files (for Q-DAS statistical packages), FLR files. Customized exporting routines can be developed on request. Curve analysis functions All curve functions are based on third order constrained spline calculations performed by a dedicated library - offsetting, comparison, best-fit, transformations. The same library provides additional functions like Fourier filtering. Advanced tools are available for handling points (re-calculation utility and parametric generation) with build in library functions.

6 CurveAnalyzer Features 2/2 Constructions and connections Alows to execute almost any type of construction or connection between geometrical elements and curves different types of intersections, projections, other constructions. 2D alignment procedure. Screen set-up Standard zoom and pan capabilities, easy to manage the visualization parameters of the objects in order to make them appear as requested. Dimensioning Standard set of dimensions, all with graphical support. Very flexible for angle evaluations. Automatic recalculation of all dimensions in current alignment. Tolerance field for curves may be constant or variable. Reporting Number of predefined graphical formats. Reports are I get, what I see, so that no additional handling is needed (except the tolerances, if needed, must be typed in manually). Easy to export the dimension data for external reporting or statistical evaluations (interfaces to Q-DAS products, EasyStat and FlexReport) Macro Macro s are powerful tool for automating the calculations and evaluations. This feature allows to memorize an unlimited number of operations and to execute them. Using macro it is easy to make work CurveAnalyzer together with your measurement software, so that you can shift evaluation procedures to CurveAnalyzer, without splitting the operational sequence.

15 CurveAnalyzer Functions 1/2 Overview -Various functions available for handling of Geometrical elements and Curves. Basic transformation functions, including 2D alignment. (each function may have number of sub-options). Examples: Geometrical elements Curves Transformations

16 CurveAnalyzer Functions 1/2 Overview Dimensioning and reporting. All basic dimension supported. Number of pre-defined reporting formats with part data table and customer logo. Additional report formats may be added by request. Dimensions Reports Currently supported languages : Italian, English, German

17 CurveAnalyzer - Applications 2D profile measurements of any kind : radiuses, chamfers, special formed transitions on shafts, prismatic mechanical parts, plastic parts, fusions. In all cases where graphical reports is an important part of the evaluation. Special geometry cams (different types), chain gears, blades (profile and / or base),special profiles on injectors or valves. Especially where best-fit and 2D profile comparisons with excellent reporting quality are requested. In many cases may substitute classical profilometers (especially if used with scanning sensor) for macro features accessible by the CMM probing system Using CurveAnalyzer on 3D CMM allows to evaluate profiles related to generic features and / or alignments.

18 CurveAnalyzer Source data 3D CMM s equiped with touch trigger or scanning probe Optical measuring machines Profilometers Any other device that produces curve point sequence output

19 CurveAnalyzer & PC-DMIS CurveAnalyzer due to its easy integration into PC-DMIS is suitable tool for profile evaluations of any kind. It is possible to include a call to CurveAnalyzer from a PC-DMIS PP, executing a macro, so that once the macro is created, no manual access to CurveAnalyzer is needed any more. CurveAnalyzer + PC-DMIS Pro. Verifying 2D profiles in scanning mode using Auto Vector Point (Needed nominals). May be used also to measure master and comapre parts to it CurveAnalyzer + PC-DMIS CAD and CAD++. May be used as report generator and as substitution of the Analysis window
